There's a companion app out which allows you to handle class hall missions whilst away from your pc.

Here is a short video that shows the main features of the app itself:

And have to say it runs decent, tried it out a few times, worth mention is that for some reason the sound can't be turned off in the app itself for some reason so be aware and turn media sounds off so your colleagues don't get a heard attack.
This is the EVE app, all over again! Train up!
You can progress your missions and research items at your camp, usefull.
I like it :) been using it the last day now. Remember to chose right server when signing up :)
Especally usefull if you have more chars. That way you don't need to log them on to progress the order hall.
